05 & 06 wrangler has recall for the exact problem my 03 has. Parking pawl slides out of the brackets and then vehicle won't go into park allowing it to roll into danger and possibly kill someone. I have watched several videos on this issue and the 03 is the same as a 05 and 06. This is just as dangerous on the 03 as it is a 05 and 06 and potentially cause an accident and kill individuals.
According to internal sales brochures and advertisements the 2003 Jeep Wrangler rubicon is supposed to be the most capable off road Jeep ever. My Jeep has been nothing but problems, which consists of 2 broken axles, faulty brakes, faulty parking brake, faulty u-joint clips, faulty wheel bearing. After paying the dealer to replace parts that should have been covered under warranty, then realizing that they failed to replace another failed part, called to ask about a workaround until the needed part came in. The advice given was to remove the broken axle shaft and drive without it. This caused brake and wheel bearing failure. An attempt to get the dealer to take responsibility for the repair cost took some time to get resolved. Finally, they fixed the problems and voided the manufacture's warranty. …
I have had the vehicle for 5 months. Appr 4 weeks ago my automatic shifter was stuck in park. After a total of 4 days at the dealership they replaced the entire shifter assembly. 2 weeks later the vehicle died on the side of the road stranding my family 130 miles from home. It was decided by the dealership that there was a blown fuse caused by an electrical short of some kind. After an entire week at the dealership they replaced the main computer and some misc. Wiring (all warranty work). The day after I got the vehicle back it died again, this time stranding my family 90 miles from home. The dealership says that there's still a short causing the fuse to blow. After another week at the dealership they replace a wiring harness that they say is bad. Again it is covered under warranty. The day that I drive home with the vehicle my brakes go out. …
Vehicle: 2003 Jeep Wrangler sport since purchasing the vehicle in 2003, I have had problems with the transmission. Automatic transmission shifting from 2nd to 3rd, sometimes higher would cause vehicle to wind up and then harshly shift into gear. Other times, the transmission would not engage at all. Have taken vehicle to dealership several times for repair (under warranty), three times they couldn't find the problem in the computer. They replaced converter most recently. Today, was driving in vehicle and suddenly transmission problem reappeared 1000 times worse - wouldn't accelerate beyond 30 MPH, then no higher than 20 MPH, and then 10 MPH until it wouldn't engage at all. Was stranded approximately 40 miles from home. Had vehicle towed to dealership and am waiting for them to look at after long holiday weekend. …
Tl contact owns a 2003 Jeep Wrangler. The contact stated that when he depressed the clutch pedal, his foot would strike the clutch pin and knock it loose. This caused clutch failure and prevented him from shifting gears. He would have to exit the vehicle to put the pin back in place. The failure only occurred when his foot struck the clutch pin. The contact had not taken the vehicle to the dealer; however, the dealer stated that they would inspect the vehicle. The contact further stated that the hydraulic clutch pedal bin would fall straight down as if his foot slipped off the pedal. The current mileage was approximately 57,000 and failure mileage was approximately 49,000.
Dt: consumer stated the clutch master cylinder failed on a 2003 Jeep Wrangler. This occurred on June 23, 2005. Consumer had no problems prior to this failure. The clutch activation rod pulled away from the master cylinder, causing the failure. Consumer took the Jeep to the dealership. The Jeep had 37,000 miles on it, and the dealership did nothing about it because it was not under warranty. Consumer tried to tell the dealership that this was a safety issue, but the dealership insisted it was not covered under warranty. Consumer had to order the master clutch and the slave cylinder to replace it himself. The clutch failed while the consumer was driving the vehicle.
The rear differential on my 2003 Jeep Wrangler is getting water in it from just driving in the rain. The dealer fixed the worn ring and pinion and bearings from the water damage but they did not fix the main problem, which is the water getting in the rear differential. About a month later the same bearing problem started occurring. Daimlerchrysler is refusing to fix the problem again because they say it is customer abuse. I have done nothing but drive the Jeep on the road. This is not customer abuse. Daimlerchrysler will find any excuse not to honor their warranty.
I have a 2003 Wrangler with a 5-speed manual transmission that suffers from intermittent problems where shifting gears is difficult if not impossible. The problem occurs most often when accelerating while shifting from 2nd to 3rd gears, and when attempting to downshift from 5th to 4th gears at highway speeds. If the vehicle does shift a grinding/banging noise is heard. I have had the local dealer look at it 4 times and they have not been able to duplicate the problem(s).
2013 Jeep Wrangler. Consumer writes in regards to intermittent engine problems, while driving up hills acceleration speeds decrease. The consumer stated upon driving up hills, the check engine light illuminated. The consumer stated after doing some research online, it appeared that another model was recalled for the same problem. Owners indicated the cam shaft sensors and dynamic sensor control needed a TCM update.
Automatic transmission intermittenly does not provide a positive gear position lock. Vehicle slips into neutral from drive. Transmission also will not properly lock into park position making it where you can not remove the key from the ignition. Taken vehicle back to dealership twice and they can not find the problem. Concenered the vehicle could slip into reverse from drive accidently.
